BackgroundSex and age may affect the pathogenesis of coronary heart disease, such as cardiovascular risk factors, treatment and prognosis, but this information is not well known.MethodsThis was a single-center retrospective cohort study. Patients with unstable angina pectoris between January 2013 and June 2018 were included and stratified into 4 age groups (<55, 55-64, 65-74 and ≥75 years). The cardiovascular risk factors profile, treatment and in-hospital prognosis differences by sex and age were explored.ResultsThis study included 5,908 patients (2,198 women). The women were older than the men (mean age 67 vs. 62 years). Approximately 2 of 3 patients had ≥3 cardiovascular risk factors. Men were more likely to be smokers, and women had a higher level of total cholesterol, low-density lipoprotein cholesterol and high-density lipoprotein cholesterol. Hypertension, diabetes and chronic kidney disease were more frequent in women ≥ 65 years old than in similarly aged men. Men and women less than 65 years of age had more frequent family history of coronary heart disease, higher body mass index, higher fasting plasma glucose, and higher lipid levels, especially for patients <55 years of age. More women tended to receive medical therapy than men (51.6% vs. 42.8%, P < 0.01). The overall incidence of in-hospital major adverse cardiovascular events was higher in men than in women (4.1% vs. 2.6%, P < 0.05), whereas there was no sex difference in the in-hospital cardiac mortality (0.2% vs. 0.2%, P > 0.05).ConclusionsWomen had higher cholesterol levels, and were less likely to undergo revascularization therapy than similarly aged men, and elderly women had a higher prevalence of hypertension, diabetes, and chronic kidney disease than elderly men. In-hospital major adverse cardiovascular events were lower in women than in men; however, there was no sex difference in the in-hospital cardiac mortality.Copyright © 2020.
